    filechooser: Prevent random completion popups
    
    It is very irritating when the entry completion popup
    appears not in response to user input in the entry.
    In particular, when that happens right as the dialog
    is shown.
    
    To prevent that, temporarily disable completion
    when setting the entry text programmatically.
